Zirconium Dioxide

ZrO₂

99.99% % pure

Form:  This material is supplied as 1 - 4 mm sintered granules.

Applications:  ZrO₂ is a high index, low absorption material used for coatings in the near-UV to IR regions (300 nm - ~8 microns). Dense layers with exceptional hardness can be deposited by e-beam evaporation or sputtering. Typical applications include bear-UV laser AR, dielectric mirror designs, multi-layer coatings for laser mirrors (combining ZrO₂ and SiO₂), and beam-splitter AR coatings (combining ZrO₂ with Al₂O₃ and MgF₂). Zirconia is among the oxide compounds whose tendency for inhomogeneous index gradients can be reduced by the introduction of foreign oxides. By introducing titanium oxide, silicon dioxide, magnesium oxide and other oxides Zirconia thin film properties are enhanced.
